Specification of Letters Patent.

Patented Feb. 10, 19 14.

Application filed July 17. 1912. Serial No. 710,096.

To all whom it may concern Be it known that I, RICHARD J AMEs TAY- non, a subject of the King of Great Britain, residing at Regina, in the Province of Saskatchewan, Dominion of Canada, have invented certain new and useful Improvements in Grain-Spouts for Threshing-Machines, of which the following is a specification.

My invention relates to improvements in grain spouts for threshing machines and the like, and the object of the invention is to devise asimple and effective grain spout which will be adjustable and which can be varied in length to suit difi'erent requirements.

Figure 1 is a side view of the spout showing the portions extended. Fig. 2 is a side View of the device showing the portions telescoped. Fig. 3 is a side view of the catch mechanisms for holding the second portion of the spout in position. Fig. 4 is a plan view of a section of the spout showing the collar surrounding the portions.

Like characters of reference indicate corresponding parts in all the figures.

1 is the portion of the spout pivotally secured to the hopper 2 of the threshing machine.

3 is the portion of the spout telescoping on the portion 1.

4 is a. collar surrounding the portions 1 and 3 but independent thereof and held in position by the connecting bar 5 which is connected at one end with the depending port-ion 4 of the collar and at the other to the upper end of the portion 1.

7 is a rod pivotally connected to the depending portion fi e designed to hold the spout at the required height.

8 is a collar surrounding the upper end of the portion 3 and having the depending portion 9 in two parts suitably held together surrounding the connecting bar 5 and extending below the same, said connecting bar 5 having a series of notches 5 in the lower surface thereof.

10 is a bell crank lever having a hooked end 11 designed to engage the notches 55" on the lower surface of the bar 5, Said bell crank lever being pivoted to the depending portion 9 of the collar 8. 12 is the other end of the lever and 13 is a rope secured thereto for pulling the hooked end 11 of the bell crank lever 10 into engagement with the notches 5 in the bar 5.

11 is a spring for holding the hooked end 11 in engagement with the notches 5 From the above description it will be seen that the length of the spout can be varied to suit the different requirements, and can be held in any desired position by the hooked end 11 of the bell crank lever 10 engaging the notches 5 in the lower surface of the'bar 5. The catch can be released by simply pulling on the rope 13 and the spout can then be adjusted to any suitable length; when the rope is released the hooked end of the bell crank lever will again spring back into a not-ch 5.

A grain spout constructed according to my invention will possess the advantage of being adjustable and will thus obviate the difliculty that occurs with the spouts at present in use. These spouts cannot be varied in length and consequently it is diflicult to vary the inclination of the same. Therefore when wet grain is run through the spout it is clogged, whereas with a spout constructed according to my invention the length and inclination can be varied and hence wet grain will not clog the spout. Further my spout will be much more convenient to handle than those at present in use.

As many changes could be made in the above construction and many apparently widely differentembodiments of my invention, within the scope of the claims constructed without departing from the spirit or scope thereof, it is intended that all matter contained in the accompanying specification and drawings, shall be interpreted as illustrative and not in a limiting sense.

What I claim as my invention is:

1. A grain spout for threshing machines, comprising a portion suitably secured to the hopper of the threshing machine, a second portion telescoping on the portion cured to the hopper, a collar surrounding the two portions having a depending portion, a suitable connection between the de pending portion and the upper end of the portion secured to the hopper guiding the second portion, a second collar surrounding the second portion and secured thereto and having a depending portion surrounding the connection between the collar and the first mentioned portion secured to the hopper, a bell crank lever pivoted to the depending portion of the second collar having a hooked end, said connection between the first mentioned collar andthc portion of the spout secured to the hopper having a series of notches in the lower face thereof, a spring for holding, the hooked end of the bell crank lever in engagement with the lower face of the connection and suitable means connected to the other end of the bell crank lever for throwing the hooked end out of engagement with notches in the lower face of the connection as and for the purpose specified.

2. A grain spout for threshing machines comprising a portion suitably secured to the hopper of the threshing machine, a second portion telescoping on the portion secured to the hopper, a collar surrounding the two portions having a depending portion, a suitable connection between the depending portion and the upper end of the portion secured tothe hopper guiding its second portion, a second collar surrounding the second portion and secured thereto and having a depending portion, a bell crank lever pivoted to the depending portion of the second collar having a hooked end, said connection between the first mentioned collar and the portion of the spout secured to the hopper having a series of notches in the lower face thereof, a spring for holding the hooked end of the bell crank lever in engagement with the lower face of the connection and suitable means connected to said bell crank lever for throwing the hooked end thereof out of engagement with the notches in the lower face of said connection as and for the purpose specified.

3. A grain spout for threshing machines, comprising a portion suitably secured to the hopper of the threshing machine, a second portion telescoping on the portion secured to the hopper, a collar surrounding the two portions having a depending portion, a suitable connection between the depending portion, and the upper end of the portion secured to the hopper, a second collar having a guide through which said connecting portion extends, and means on said second collar adapted to engage said connection to hold said second portion in desired adjusted position.

In Witness whereof I have hereunto set my hand in the presence of two witnesses.

RICHARD JAMES TAYLOR.
